We have a roof lantern in our extension.
During the summer, the bloody flies/other insects come in when we have the bifolds open, buzz around and get stuck up there.
Come the morning when we come downstairs, the floor is like a fly graveyard that needs hoovering and looks pretty gross.
Anyone else have this issue? Wondering what anti-insect measure I can set up to put up in the roof lantern to deter them.
